> Unfortunately I don't think this is merely cognitive bias. It's actually built into our legal system at a pretty fundamental level: machines are held to a higher standard than humans when it comes to failures with grave consequences.

Well, laws reflect culturo-cognitive biases, don't they? And also they evolve.

For the last part, that seems to generally be a wise "bias": when a machine fails, chances are good that all the identical machines will fail the same way.

When a human err, chances are good that this won't be in a way you might expect to identically happen in all its peers, although common cultural biases can happen obviously.

Also so far, our machine are far less expected to self-correct their behaviors when they err, especially regarding some untold social exceptions that were not met through some unexpected side effects.

Ultimately, machines don't care of consequences of their acts because they don't have any feeling of responsibility to someone they love, not even themselves.
